Rocket Fuel

Since its introduction in 2013, the SmartAdvantage Powertrain has proven to be the most fuel-efficient powertrain in the trucking industry. Today we are utilizing downspeeding to get up to 7% better fuel economy than competitive integrated powertrains.

In response to customer needs, Cummins and Eaton® have expanded the SmartAdvantage Powertrain lineup to include both the original small-step overdrive transmission plus a new direct drive version that delivers exceptional fuel economy in less-than-truckload (LTL) and regional linehaul operations. This addition will help fleets achieve productivity challenges across a broader spectrum of operating conditions with specific duty cycles. The SmartAdvantage Powertrain is the only integrated powertrain to offer both options.

Our interactive SmartAdvantage Selection Guide walks you through a step-by-step process to select the best SmartAdvantage Powertrain for your trucking operation based on factors such as target engine speed, route terrain and vehicle weight.

The SmartAdvantage Powertrain features your choice of Cummins X15 or ISX12 engines with SmartTorque2 (ST2) and SmartCoast, paired with an Eaton Fuller Advantage® 10-Speed automated manual transmission (AMT). The engine and transmission share critical data, determining the torque required to deliver the power level that drivers demand.

The X15 SmartAdvantage Powertrain optimizes shifting based on grade, vehicle weight, engine torque and throttle position. The result is error-free, guess-proof shifting − making every driver in your fleet as efficient as your best driver.

At least one version of the SmartAdvantage Powertrain is currently available at every major truck OEM, so even if you are running a mixed fleet you can spec a single powertrain.
